Find the de broglie wavelength λ for an electron moving at a speed of 1.00 x 10^6m/s. (note that this speed is low enough that the classical momentum formula p=mv is still valid.) recall that the mass of an electron is me=9.11 x 10^−31kg, and planck's constant is h=6.626 x 10^−34j*s. express your answer in meters to three significant figures.

De broglie wavelength will be 0.727 nm

Explanation:

We have given speed of the electron

Mass of the electron

Plank's constant

We have to find the De Broglie wavelength

De Broglie wavelength is given by

So wavelength will be 0.727 nm

f=ma newton

f=100x2.5=250n

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
